Phaetus Dragon HF mount for Creality Ender 3 Max Neo

I had no intention to publish this model & it was for my machines but by request here is the first version. It's printed from PETG & after 300+ hours with no problems I decided it could be useful for others. The Dragon HF is known for heat creep and being difficult to cool and this mount was designed with that in mind. It might not be a looker but it's all performance for PLA and PETG printing. Prints as slow as 15mms and 5mm3 flow rate have been tested for many hours without any jams or clogs. It's simple to print with just 2 main parts and a fan duct. It's a drop-in replacement that doesn't require any firmware updates & retains the exact XY geometry. The hotend sits higher up on the bracket from the original for a better center of gravity & frees up an extra 10-15mm of Z height. (requires firmware update if you want that extra height. I haven't updated mine). It also requires a new 5015 24v blower fan to cool the Dragon. The mount was designed with form fitting bracers inside to make sure the hotend doesn't rotate or slip or move. It uses the stock part cooling fan. It requires 9x M3 screws and nuts to assemble together. The part cooling fan requires 4x M2 screws and nuts. I just got an Amazon bolt & nut kit. The 4 nut seals are press fit to allow the front piece to be bolted on after the main back piece has been mounted. The 2 nut inserts on the side of the back piece for the part cooling fan have no seal and the nuts in it can fall off if tilted during assembly. I rolled together a bit of black electrical tape and jammed it in with a small screwdriver after putting the nut to make sure it wont slide or fall off. The CR touch probe can be annoying to tighten & the wire for it should be connected through the opening first before mounting it. The tolerances are tight but everything should fit with a bit of patience. I had to slightly file the inner edges of the 2 mounting screw protruding tubes on the metal bracket to allow clearance of the hotend and for the front piece to fit flush… maybe ½ a millimeter. The fan duct should be printed at an angle with supports. The other pieces are flat so no supports needed. I haven't put together clear instructions at the moment but overall it's not too difficult to assemble & if you have any questions please post them down here!

UPDATE Do not exceed 230°C - 240°C with this mount just to be safe. Only use for PLA printing. Even though the mount is solid and has a firm grip on the hotend, the bottom part near the heat block can start melting after 240°C.
